length of the base = 6 /tan(14.5) = 23.20 = 23 inches

if you need the hypotenuse ( length of the angled board) that would be 6/sin(14.5) = 23.96 = 24 inches.

Answer:

P = $\frac{4}{25}\\$

Step-by-step explanation:

Big circle area:

$A=\pi r^{2} =\pi (10)^{2} =100\pi$

Smaller circle área:

$A=\pi (4)^{2} =16\pi$

Probability:

$P=\frac{16\pi }{100\pi } =\frac{4}{25}$

Hope this helps

A circle that originally had a circumference of 31.4 cm, now has a circumference of 15.7 cm. What happened to the radius? It was

PolarNik [594]

The radius was divided by 2.

31.4 = 2pi * r

31.4/2pi = 15.7/pi

15.7 = 2pi * r

15.7/2pi = 7.85/pi

(7.85/pi) / (15.7/pi) = 1/2
